hdparm

Secka mi gad gledam originalne DVD filmove…

[code]stefan@stefan:~$ sudo hdparm /dev/hdc
Password:

/dev/hdc:

OK, DMA je vec enabled, ali da bi mi ova podesavanja bila prihvacena pri bootovanju morao sam da editujem /etc/hdparm.conf skriptu. Evo moje /etc/hdparm.conf skripte, pa mi recite gde sam pogresio, posto mi originalni DVD filmovi i dalje seckaju?

Pogledajte poslednjih 5 redova. To sam ja unosio.

Ne znam vise sta da radim? 😥

kod mene je stanje ovakvo
# hdparm /dev/hdc

/dev/hdc:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument

pokushaj stavi ista podeshavanja

Kako da stavim ista? Kako da promenim IO_support na 32-bit i unmaskirq na “on”?

[LYb]

man hdparm pa ces videti i sam kako.

Da ne budem dezurni namcor, pogledaj
http://gentoo-wiki.com/HOWTO_Use_hdparm_to_improve_IDE_device_performance

To je medju prvim linkovima koje dobijes kada na google-u trazis “hdparm gentoo” – ne, ovo nije pokusaj forsiranja gentoo-a, nego stoji cinjenica da gentoo ima neverovatan community i da na taj nacin mozes da nadjes gomilu odgovora nevezanih za distribuciju koju koristis.

I dalje secka. 😥

[LYb]

Probaj sa ukljucenim unmaskirq. Opcija -u1.

Nego, sad bas gledam originalni post i onu skriptu… pa tamo sve definises i sve ti je objasnjeno u najsitnija crevca (uzgred, nisu mi jasni “tih 5 poslednjih redova” koje si sam ubacio, nemaju smisla, a i iskometarisani su)… ubaci ovo:

/dev/hdc {
dma = on
interrupt_unmask = on
io32_support = 1
mult_sect_io = 32
}

u ono gore mozed sa ubacis i
transfer_mode = , s tim da je :

64 65 66 67 68 69 70
za UDMA 0 1 2 3 4 5 6, tim redom (npr za UDMA4 je 68, za UDMA2 je 66 i tako dalje)

E, kad to sve uradis, javi nam sta ti kaze
hdparm -iI /dev/hdc

[BrokeBody]

Dodao sam ono sto si mi rekao (poslednjih 7 redova).

Pa sam kucao u konzoli:

/dev/hdc:
setting unmaskirq to 1 (on)
unmaskirq = 1 (on)
stefan@stefan:~$ sudo hdparm /dev/hdc

I dalje secka. 😥

A da mozda nije problem u tome kako su mi kablovi prikaceni u kucistu? Neko mi rece da bi i zbog toga moglo da bude?

[DVSoftware]

to je verovatno rekao windows struchnjak… nego sada ti je IO_support = 0 (default 16-bit)

[BrokeBody]

Ju…! 😯 Gle’ stvarno…?!? Ponovo 16-bit? 😕 Cek, cek…

[code]stefan@stefan:~$ sudo hdparm -c1 /dev/hdc
Password:

/dev/hdc:
setting 32-bit IO_support flag to 1
IO_support = 1 (32-bit)
stefan@stefan:~$ hdparm /dev/hdc

/dev/hdc:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument
stefan@stefan:~$[/code]

Evo ga. Ponovo na 32-bit, al’ i dalje secka. 😥

Primetio sam nesto… Kad restartujem racunar meni se IO_support vrati na 16-bit.

Na Ubuntuovom sajtu mi pise ovo:

Enabling DMA

To enable DMA, you need to use the hdparm command and the configuration file hdparm.conf.

These instructions assume that you are trying to enable DMA on hdc, usually the CD-rom drive.

1.

See the what the settings are on /dev/hdc

sudo hdparm /dev/hdc

2.

If you get a line like using_dma = 1 (on), DMA is already enabled. Skip to step 4 to see if it has been enabled at boot time.
3.

Enable DMA on /dev/hdc

sudo hdparm -d1 /dev/hdc

4.

You have now enabled DMA for the drive. However, in order for the settings to be automatically applied at boot there you need to edit the /etc/hdparm.conf} script. To do this use this command: sudo gedit /etc/hdparm.conf

Add the following to the end of your hdparm.conf

/dev/hdc {
dma = on
}

Mozda ja nesto nisam lepo uneo u /etc/hdparm.conf skriptu, pa zbog toga i nece da mi prihvati IO_support na 32-bit pri bootovanju? ❓

[BrokeBody]

Evo jos jednom moje skripte. Necu sada da kopiram celu, samo ono sto sam ja unosio (pretposlednje) po preporuci sa Ubuntuovog sajta i ono sto mi je LYb rekao da unesem (poslednje)…

[code]/dev/hdc {
dma = on
}

dev/hdc {
dma = on
interrupt_unmask = on
io32_support = 1
mult_sect_io = 32
}[/code]

Help meee…?!? 😥 😥 😥
